Answer:
Not that I'm a chemistry expert but mathematically,The total weight of the bar is directly proportional to the known weight of the bar and the given percentage. I worked it out and found that the the total weight of the bar is 30 ounces. This is how I did it
Step-by-step explanation:
80:24
100:n
80(n)=100×24
A little equation and after it's solve the variable (n) will be equal to 30
The unit is added after calculations so that's how the answer is <em><u>3</u></em><em><u>0</u></em><em><u> </u></em><em><u>oun</u></em><em><u>ces</u></em>
2x-1=5-6x
2x=5-6x+1
2x=-6x+6
2x+6x=6
8x=6x=6/8
x=3/4
Oh hey, its me again.
Answer:
he has to make a sale of $750
Step-by-step explanation:
first job pays $880 per week
second job pays $790 per week
amount first job is paying more=$(880-790)
=$90
therefore,12% should $90 if he wants to make an equal amount as the first job is paying therefore,sale he has to do
12% of x=$90
12/100*x=$90
x=90*100/12
x=9000/12
x=$750
thus he has to make a sale of $750 to earn a 12% comission of $90
